Specification of Letters Patent.

T 0 all whom it may concern: Be it known that I, Janos Sonrronrnnn, asubject of the Emperor of Austria-Hungary, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented. certain new and useful Improvements in Mop-Nringers, of which the following is a specification.

My invention relates to mop wringers, and has for improvements in its object the production of a. device of this character which will be of improved construction and efli cient in operation. V

A turther object is theproduction of a mop wringer adapted for attachment to an ordinary pail, and which will be so designed as to adapt the same for adjustment to pails of ditlerent sizes, and which will be adapted for readyand expeditious attachment or detachment. e

Other objects will appear hereinafter.

With these objects in view consists in the combinations and arrangements of parts hereinafter described and claimed. I

The invention will be best understood by reference to the accompanying drawing forming a part otthis specification, which, i a r I Figure 1 is a perspective view of a mop wringer embodying my invention, the same being shown applied side elevation of the construction shown in Fig. 1, Fig. is a top plan view ot the-construction shown in Fig. 1, and Fig. 1; is a detail front elevation of one end of the band which is adapted to embrace the pailiin con junction with which the device is employed.

The preferred form of construction, as illustrated in the accompanying drawing, comprises a metallic band 1 which is adapted to embrace a conventional pail 2, as shown. The band 1 is provided at one end with an end piece 3 having key-hole slots 4: therein for eleasable engagement with headed studs 5 projecting from said end of said band, as clearly shown in Fig. 4. A plurality of slots 4. is provided in the end piece 3 for engagement with the studs 5in order to adapt said end piece for longitudinal adjustment upon the band 1 so as to permit or the device being used upon pails of various sizes. lhe ends of the band are connected togeher by means of a bolt 6 w ich projects throughthe outwardly turned Application rues February 8, 1915.

I understood.

Arising from opposite sides of the band 1 ally secured bers 8 is a U-shaped member the invention and in V of the memberslG are T he bights' of Patented Nov. 3e, 1915. Serial no. 6,840.

end of the end piece 3 and which ded in the outot the band, as

perforated engages with a slot 7 provi wardly turned ad acent end clearly shown in the several views. thumb nut 6" cooperates with the bolt 6 in connectmg the ends of the band, as will be readily are supporting members 8 rigidly secured at their lower ends to said band. Rotatably mounted between the upper ends of the members 8 is a roller 9. Rigidly secured to and projecting obliquely downwardly from the supporting members 8 are arms 10 to the outer or lower ends of which are pivotlinks 11. Rotatably mounted between the outer ends of links 11 is a roller 12 to which is fixed a crank handle13 which permits or manual rotation of said roller.

Cooperating with the supporting memlt, the respective ends of which are tulcrumedat 15 to the outer sides of said members 8, as clearly shown in the several views. Cooperating with the links llis a U-shaped member 16, the respective ends of which passloosely throughpertorated laterally projecting cars 17 carried by said links, as shown. T he ends connected with the ears 1'? by means of nuts 18 and 19 which are threaded upon said ends ot-themember 16, helical compression springs 20 being interosed between the nuts 19 and said ears. the members 1a and 16 are pivotally connected together by means of a sleeve or tube 21 loosely embracing the same, as shown. I I

The constructionis such, as will be seen, that when the member 21 is moved tor-I wardly and downwardly to the position will be carried into operative relation with the roller 9 and yieldingly held in engagement therewith by reason 0 the tension or pressure of springs 20; Furthermore, the arrangementis such that, inthis movement of the member21, as the roller 12 reaches a position in contact with the roller 9, the levers 14: and 16 will be on dead center, that is the points 15, 17 and 21 will be positioned in the same line; continued downward movement of the member 21 carrying said members 14 and 16 past the dead center position against the influence of the springs 20. After the dead center position has been roller 12 in passed, itis of course clear that, the pressure of the sg'irings 20. will act to turther move H v n' the members ll and lb 111 this dn ection until the same contact with a stop which will be constituted by the upper edge of the pail, and thus serve to auton'iaticaliy hold the operative position. In moving said roller from operative position, the reverse operation is, of course, resorted to, namely, moving the member 21 upwardly to the full line position shown in Fig. 2. The mop which it is desired to wring is placed between the rollers 9 and 12 when the latter is in inoperative position or spaced from the roller 9, whereupon the member 21 is moved downwardly in order to carry said roller 12 into engagement with: the The handle 13 isthen rotated to carry the mop head outwardly, in which operation the wringing is efl ected, as is readily understood.

Provided at the inner sides of the members 8 are angularly positioned finger-s22 which serve to hold the mop head centrally between the rollers in the wringing operation. The lower ends of the attached portions of fingers 22 are bent inwardly, as at 23, in order to constitute stops adapted for engagement with the upper edge of the pail in order to limit the downward the device relative thereto. 7 he pail is held-secure upon the ground or oor during the wringing operation by means of a member 24, the ends of which are pivotally engaged with eyes :25 projecting from opposite'sides, of the band 1. The outer end portion or bight 26 of the member 24: constitutes a foot rest whereby the device may against the ground tl'irough foot pressure, as will be readily understood.

lVhile I have illustrated and described'the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but

esire to avail myself of such variations and modifications as come within the scope of the appended claims.
